Hi, I recently post advd rip of my own in non horror releases(Survive) and a moderator changed it name and it says nuked dvdrip?

What does it mean exactly?!

Thx

It means the ripper has made a uncorrectable mistake while encoding, and that the rip will be lower quality than it should be given the source because of this mistake. It's used to describe messed up group rips and grounds for a proper by another group actually, but people normally use it to describe a flawed rip.

Main reasons are:
*BAD IVTC* - They've forgotten, or careless didn't bother to convert an artificially high framerate to the correct fps. This is only applicable to NTSC dvds/material that reports 29.9fps on the DVD, but the content is actually 23fps and the DVD uses a methods to artificially up the framerate to NTSC tv framerate. The problem with not doing this is that quality is significantly reduced, as instead of encoding the correct number of frames, to make up the framerate, the same frames are duplicated which means a) instead of encoding 23fps, it wasted video data in encoding nearly 30fps b) it can and normally does give a stuttering playback because you effectively see the exact same frame several times a second.
*BAD CROPPING* - You should *always* crop of black boarders for several reasons. The first is because it reduces the quality significantly, since you have to encode a larger res that you should. Secondly, encoding solid colours takes a lot of video bitrate so don't forget to crop people!!! Ideally there should be no boarders, but a couple of pixels is acceptable..
*BAD DEINTERLACING* - They've forgotten to remove interlacing which makes playback almost unwatchable on a PC
*BAD AR* - The aspect ratio is totally foobar, ie. squashed heads, or fat people
*BAD RES* - The res is way too small (under 512 normally), which means when you resize it, the thing looks crap. Don't go below 512!
*BAD BITRATE* - The bitrate is just far too low to get decent results. You should never go under 800kb/s unless you get a high bits/pixel

Using a correct ripping method (ie. gknot following the doom9 guides) will make any of these an impossibility.

For these reasons in addition to all the info in the Sticky topics of the release section a rip will be moved to lesser quality. The thing about the dual format of higher/lower sections is that its done regarding quality, not nescessarily source. Poor authored dvds maybe moved to lesser quality too. If you have heavy ghosting or something in a rip, then it should also go in lesser quality.

I checked up on it, the reason for it is:



With 4:3 material, you have a larger visible space that means you simply need as much bitrate as possible, unfortunately, 737kb/s is too low. However this isn't really a proplem, the problem is the resolution, its way too small, you shouldn't have gone under 512 (in this instance, you are allowed to drop down to 496 [i think it is, there's a high res in the 400s that allows 4:3], this is just below your target res and thusly you might have been able to pull it off, but below 400 will make it very hard to watch). When this rip will be resized to fullscreen (even on a low desktop res, let alone 1600x1200(, it will be poor quality, very blocky due to the low bitrate. The bitrate for the audio is also extremely high, given the video was suffering, you should drop that down to 96 kb/s VBR, and try and get the video looking as good as you possibly can.

I think though, with the source, you were going to find it nearly impossible to get decent results with a 1cd release. It wasn't really an attainable target, so its not so much your fault as a ripper or anything, the "nuked DVDrip" is to show people who are going to download, if you download this, expect the quality to be much lower considering the rip is from DVD.

Yes I was afraid of that but I watched the rip before posting and it isnt bad ! Oh well I did it wit AutoGknot as always but perhaps shoul I specify 2 cds ! I was thinking of doing 2 cds but then the original dvd isnt that perfect either so I though its a lost of space!

Well I typed it when sorting out the topic title on the fly (you didn't fill in the genre or source), when I reached the source, I noticed the lower quality specs so I put nuked. Didn't mean anything by it or anything

If you prefer, change it to "LowQ DVDrip" or something like that, just thing its worth emphasising for anyone that wants to download not to expect something they would expect from a dvd

I would have gone for the 1cd option too, and I would have written something similar about lower quality dvdrip too for myself

btw. I did a check, the "TDX guidelines" which is what groups have to abide by, but many of them are very sensible (if out of date). The rule regarding resolution, is absolute minimum of 512x for widescreen and 446 for panscan, but I don't agree with the 4:3 one myself, I think that the res has to be around 512 too.

Good template to folow. If you think nuked dvdrip is off putting, change it to lowq or something to that degree. Has the same meaning

Ok np at all!
Next time I know what/how to do ! I never thought of resolution cause I always use Autigknot and get very good results!
Thx for the explanation!
